Accurate and precise machining is crucial for manufacturing innovative products across countless industries. For decades, computer numerical control milling, commonly known as CNC milling, has revolutionized machining processes to maximize efficiency, repeatability, and capabilities. Furthermore, CNC milling services continue their rapid advancement, optimizing and streamlining operations while expanding what parts can be produced.

Understanding this advanced machining method’s core principles and applications has become increasingly important for manufacturers seeking to stay on the leading edge. So, let’s explore the critical technical aspects of CNC milling, such as the machine’s capabilities and its process, to help you make informed decisions about how CNC milling can meet your specific manufacturing needs.

How Does the CNC Milling Machine Work?

High-quality parts with great detail and finish are expected in every CNC milling service. These are accomplished through CNC milling machines equipped with rotary tools to cut away at the material. These follow instructions from a software or CAD file containing the part design’s blueprint.

The machine’s computer controls the cutters, so minimal human intervention occurs during the process. These are engineered to mass-produce components from varying materials, such as metals and plastics. The core function of these specialized machines is to remove material from the workpiece until the desired shape is formed.

How Does the CNC Milling Process Work?

CNC milling services consist of a step-by-step process, which is religiously followed to maintain accuracy and precision. Below is a basic outline of the process:

  • Designing of the part: A 3D CAD file is developed with the final part. Afterward, the design is converted into a machine-readable format.
  • Conversion of the design: The Computer-Aided Manufacturing software exports the converted design to the CNC machine program, usually in G-format. It serves as the machine’s instruction, directing every move it makes.
  • Subtractive machining technology: Material is removed from the workpiece, and the milling machine uses a rotating cylindrical tool. Depending on the milling machine, the machine can cut at different angles and move along different axes.

The final part is achieved once the machine is done, and the process repeats itself. CNC milling can consistently manufacture high and low volumes of highly complex and intricate parts, which is its primary advantage.

Common Types of CNC Milling Services Available

Various types of CNC milling services are available, including vertical and horizontal. These are used for different kinds of materials and part sizes, depending on the project’s specific requirements.

The most common CNC milling methods include:

  • Vertical milling: The most common setup where you see the cutting tool in a vertical orientation is called vertical milling. There are two types: turret vertical milling and bed vertical milling. In turret milling, the spindle remains stationary while the turret bed moves horizontally and vertically. In bed milling, the spindle moves horizontally while the bed moves vertically.
  • Horizontal milling: Vertical and horizontal milling have the same operations, but the tool will have a horizontal orientation. These are commonly employed in creating larger parts.
  • Face milling: The cutting tool is placed perpendicularly to the workpiece in the face milling process. Its position is face down towards the top of the workpiece, so they’re used for flattening and smoothing its surface.
  • Plain milling: The cutter drive shaft is set up parallel to the cut surface, so it’s ideal for milling large, flat horizontal surface products.
